S M Krishna's gesture

I was quite amused to read that Mr.S.M.Krishna, external affairs minister, cut short his foreign visit and dashed back to India to attend the funeral of YSR Reddy. An external affairs minister interested in internal affairs! Even when he was the Governor of Maharashtra he was more interested in the internal affairs of Karnataka. Why not just make him the minister for internal affairs if he has to be humoured? And will the government of India make him pay from his personal account the cost of the recent up and down trip he made to attend YSR's funeral?
